— In-game description
12x70 Dragonbreath is a special type of shotgun shells, added in the Faction Pack DLC for Metro Last Light. It is only available in the mission Kshatriya. Unlike regular 12x70 Buckshot, these rounds are incendiary, having shorter range, but being much more deadly.
12x70 Dragonbreath have the same appearance as the normal buckshot in Metro 2033 - red shells (though they appear blue when loaded in the Shambler). They offer increased damage output, as well as a chance to ignite an enemy, resulting in even more damage over time, Like the Last Light version of MGR. However, the incendiary feature does reduce the effective range of the shotgun considerably, even with the extended barrel attachment. But given the close quarters fighting found in Kshatriya they are very effective against Nosalises, Watchmen, and even Librarians - making a single shell hit easily take down a watchman, and three or four are sometimes enough for a Librarian. Their power means that even the weak starting weapon - the Ashot - becomes very powerful, easily capable of killing Nosalis hordes. The rounds become even more effective if the Duplet or Shambler is purchased later in the mission.
The Dragonbreath Shotgun shell is slightly more expensive than normal 12 Gauge shells, as 6 shots cost 7 MGRs (regular shotgun shells only cost 5 MGRs per 6 shells), but the players start with some Dragonbreath shells that can be used with Ashot.
- Real-life Dragonbreath shells are filled with magnesium shards. Magnesium is a very reactive element and when the shell is fired, the magnesium shards burn at approximately 3,000 °F (1,650 °C), producing a very bright light. There aren't any recorded uses of this type of ammunition by military, but the temperature it produces would be more than enough to set a building, or a person, on fire. Therefore, its use is banned in many places in the world, as incendiary weapons (like flamethrowers or white phosphorus shells) are considered too cruel and "barbaric" to be used in modern-day combat.
